Jack oil is one of the most commonly used tools in the industry and automotive repairs that is responsible for lifting and holding heavy objects. These jacks provide the necessary force to lift the loads using hydraulic oil. Due to the widespread use and functional sensitivity of the oil jacks, their proper maintenance is important.

The structure and function of the oily jack

The oil jack consists of several main parts: Cylinders and pistons: where the oil is pressured and the lifting force is produced. Hydraulic Oil: Power Transfer Fluid. Control valve and pump handle: to adjust oil flow and pressure. Wool bowl and gaskets: Prevent oil leakage and dust entry.

Oil jack function is based on hydraulic pressure law. By pressing the pump handle, the oil is directed to the piston and created the force needed to raise the load.

Common problems with oily jack

1. Oil leak:

is the most common problem that usually occurs due to the failure of gaskets or bowls.

2. Reduce pressure and power of lifting:

may be due to incomplete system or oil deficiency.

3. The rigid or softness of the piston movement:

can be caused by oil contamination or internal parts.

4. Non -voice:

indicates the failure of mechanical parts or oil deficiency.

The process of repairing the oil jack

1. Check and detect the problem

You must first find the oil leakage. Control the oil status and its surface. Test the performance of the pump and piston handle.

2. Dump and replace the oil

Drain the old oil completely. Use quality hydraulic oil and recommended by the manufacturer.

3. Replace the gasket and the bowl

Replace the gaskets and bowls. Note that the new parts are commensurate with the Jack model.

4. System ventilation

with the ventilation methods, remove the air in the system to optimize the performance.

5. Assembly and final testing

Set the pieces correctly. Test the jack without load and then with the load. Make sure there is no oil leak and the jack works easily.

Important Tips to Keep Oil Jack

always replace the Jack Oil on a timely manner. Keep the jack in a clean and dry environment. Avoid entering the load over the capacity of the jack. Check the gaskets and the bowls every once in a while
